Level relay HRH-8, 230 VAC
- Relay is designed to control the level of conductive liquids in wells, tanks, pools, tankers, reservoirs,... (replacement HRH-1).
- Galvanically isolated supply and guard circuits.
- Within one device, the following confi gurations can be selected:
- 2x one-level monitoring (in separate tanks)
- 1x two-level monitoring (in one tank) - pumping from one tank to another. - DIP switch selection on the front panel (8 functions).
- Adjustable probe sensitivity (for each probe separately).
- Adjustable relay switching delay (for each probe separately).
- 10 Hz watch frequency prevents polarization of the liquid and increases resistance to interference by network frequency
